alert message during build "require function is used in a way in which dependencies cannot be statically extracted"

[jbilcke-hf]

Hello, for your information I get this message when I use the library in a Next project (replicate 0.30.2 with Next 14.2.3 or Next 14.2.4 - I haven't tested older combinations):

 ⚠ Compiled with warnings

./node_modules/replicate/lib/util.js
Critical dependency: require function is used in a way in which dependencies cannot be statically extracted

Import trace for requested module:
./node_modules/replicate/lib/util.js
./node_modules/replicate/index.js

I don't know exactly the consequences, my Next app seems to work just fine despite the scary "critical dependency" message, but you might still wanna check it out as other people might come across this too.

For a bit more context, I'm using a lot (90+) of other modules in the same project like langchain etc (I hope we will see a @langchain/replicate NPM module soon by the way) but none of them trigger this, so that's weird.

I'm using replicate on server-side not client-side (ie. I'm using it for Next's API endpoints) so it runs in a Node environment.

The tsconfig.json is like this if that can help:

Hi @jbilcke-hf. Thanks for writing in. I believe that warning relates to this code which dynamically requires node:crypto as needed.

Is your project is using Webpack or Turbopack? Can you share any other details of you Next configuration?

[jbilcke-hf]

I am using Webpack, here is my project for reference: @jbilcke-hf/clapper (note: this is a work in progress so some things like the support for Replicate are not 100% finished yet)

I've just tried to create a minimal Next project to try to reproduce the issue but I wasn’t able to (a bare Next project + Replicate module doesn't trigger this warning)

Since this seems caused by a weirdness in my project, like a dependency trying to polyfill require(), I'm sorry for taking your time on this. This is probably not worth looking too much into.

The node protocol is supported now in Webpack 5.92.0. I wonder what the upgrade curve is for Webpack in Next projects… it would be nice to remove the code...
